National Park Week free Aug. 22–30

The National Park Service has set National Park Week for August 22-30, 2026, shifting the annual celebration to late summer and tying it to the agency’s 110th anniversary. The agency said entrance fees will be waived on August 25, the date of the Park Service’s birthday in 1916. The National Parks Conservation Association also pointed visitors to the Aug. 22-30 window in a post about ways to celebrate the week. NPS said the 2026 theme is “Celebrate America’s Story,” linking the event to the country’s 250th anniversary observances. ### When is the free day, exactly? August 25, 2026, is the only date in that nine-day stretch when entrance fees will be waived systemwide at parks that normally charge them, according to NPS. The agency said the fee waiver applies to U.S. citizens and residents and is tied to the National Park Service’s 110th birthday. The late-summer timing differs from recent years, when National Park Week has often been held in April. (nps.gov) NPS said this year’s observance runs August 22-30. ### Does “free entrance” mean everything at the park is free? NPS says no. The agency’s fee-free language covers entrance fees at sites that charge for admission, but other charges can still apply. (nps.gov) Park pages say those can include timed-entry charges, reservation fees, camping fees, tours or concessioner-operated services. Rocky Mountain National Park, for example, still lists timed-entry reservations for part of the 2026 season, and other parks maintain separate reservation systems for parking, sunrise access or shuttle use. (nps.gov) That means a fee-free day may reduce the cost of getting in without removing every planning requirement. ### Which parks does this affect? NPS said the waiver applies at all National Park Service sites that charge an entrance fee. (go.nps.gov) Not every unit in the system charges one, but some of the most visited parks do. Indiana Dunes National Park, for instance, lists a $25 vehicle pass for one to seven days outside fee-free dates. The National Park Service oversees 433 national park sites, according to its March announcement for the 2026 observance. (npca.org) Jessica Bowron, the comptroller exercising the delegated authority of the director, said in that release that those parks “tell the story of the United States.” ### Why is National Park Week in August this year? March 20, 2026, was the date the Department of the Interior announced the August schedule. (nps.gov) The department said the timing was meant to coincide with the Park Service’s Aug. 25, 1916, founding date and with the 250th anniversary year of American independence. The agency’s partner toolkit repeats the 2026 theme, “Celebrate America’s Story,” and says it aligns with broader 250th-anniversary commemorations. (nps.gov) ### What should visitors do before they go? NPS urges visitors to check individual park conditions, reservation requirements and local alerts before traveling. That matters in summer 2026 because some parks have separate access controls and others may have crowding, weather or wildfire-related disruptions. (nps.gov) August 22 is the start of National Park Week, and August 25 is the fee-free day. (nps.gov) Park-specific event calendars and the NPS commemorations pages are already listing details for late August programs, including National Junior Ranger Day on August 30.
